Abstract: ABSTRACT OF THE DISCLOSURE           Hospital and like equipment is decontaminated after washing, by being subjected to a short shock of hot, moist air. The temperature ranges from 350°C to 800°C, and is preferably maintained at, or above 500°C, the treatment time being a matter of seconds only.  A receptacle for the equipment may be provided with means permitting the washing of the equipment, while placed in the receptacle.  Automatic governing means is provided to shut off the receptacle from the circulation system during the wash-ing operation, and to start the circulation and the heating as well as opening a shut-off valve to the receptacle, when the washing is finished.

Abstract: ABSTRACT OF THE DISCLOSURE            For the connection of line portions made from thermo-plastic material and which diverge from the general turn config-uration, a welded sleeve is formed by a sleeve member with a coil of a resistance heating wire arranged on the inner wall.          Sleeve member has an inner portion in whose grooves is arranged the resistance heating wire and which is surrounded by an outer portion.  Ridges arranged in the bottom of the groove form bend-ing or deformation points in the turns of the coil.  On welding the sleeve, the turns expand, but due to the bending or deforma-tion points, the resistance heating wire is only deformed at these particular points and the actual turns are held in position.

Abstract: ABSTRACT OF THE DISCLOSURE      A plastic or equivalent thin film bag is rolled up inside a coiling spiral formed from a strip sheet constant force spring to squeeze out its contents completely and to produce dispensing force at all times.  The coil spring strip may be of plastic, elastomer or fibrous materials and may form a wall of the bag so that the container may be made at very low cost for storage of bulk fluids including carbonated beverages for dispensing therefrom one serving at a time.  Thus a packaging array for fluent materials comprises a thin flexible-walled container or bag having a common area with an uncoiled spiral constant force spring strip and positioned to coil up by rolling up a container bag tail inside the coil spring spiral as contents are dis-charged.  The bag is placed in a container confining the fluid bag contents to occupy a position with a height corresponding to that of the constant force coil spring spiral diameter thereby to exert by the spiral a sub-stantially constant force aiding the discharge of the contents over the entire bag capacity.  The spring carries a contents gage which shows the amount of materials left in the bag.

Abstract: ABSTRACT OF THE DISCLOSURE         A system for automatically controlling changeover between recording and recording stop, or transmission and transmission stop, and being employed in a recording or , transmitting device provided with a vibration pick-up type microphone for picking up bone-conducted voice sounds.  The automatic changeover between recording and recording stop or transmission and transmission stop is attained by control signals corresponding to impact vibrations other than voice signals uttered by a microphone wearer himself, transmitted through his bones and picked up by the microphone or another controlling microphone.  Thus when the controller detects an impact vibration within the desired frequency range, such as a clicking of teeth, the controller will effect the desired changeover.  The system is unaffected by background noise or by conversation with people nearby.

Brackets on a caterpillar-like capstan grip the bundle and hold it while turning the bundle on the stranding axis.  The bundle continues toward a second stranding point spaced particularly from the cap-stan.  The stationary (nonrevolving) stranding pints can be estab-lished by nipples or by additional, nonrevolving capstans, in which case slidable brackets are used to compensate speed differentials. The revolving capstan may rotate continuously or reverse periodi-cally to obtain different types of stranding patterns.

Abstract: ABSTRACT OF THE INVENTION A method for recording character or marking signals by multi-beam laser technique, in which the characters are recorded in multi-rastered bands in such a way that the character information is inverted, whereby the recording surface is illum-inated by the laser beams at each location that do not comprise characters or marks,  In character locations the surface is not illuminated.  The gaps between adjacent bands are illuminated by separate band gap illuminating laser beams.  By using this method the electrophotographic image recording can be solved by means of conventional inexpensive positive copiers in which image reversal does not take place.  The apparatus for carrying out the method comprises a Bragg cell, a control unit for pro-ducing several raster scanning laser beams, and oscillators for generating additional band gap illuminating laser beams.          An inverting unit is inserted in the path between the information source and the control unit to perform electronic image reversal.

Abstract: Abstract of the Disclosure A modular motor and drive unit for use in an elec-trical device, such as a hand food mixer, wherein the motor is characterized by a low-cost speed control which is capable of providing a large number of discrete motor speeds.  The speed control, rather than utilizing a multi-contact switch connected to the field coil by individual taps, has approxi-mately twenty field coil continuous loop taps wound over a bobbin spindle in side-by-side relationship with a wiper contact being slideably movable relative thereto along a path from which the insulation has been removed.  Positions of the wiper contact may be determined by replaceable detent elements provided with different detent patterns providing different series of motor speeds whereby the same motor and drive module may be provided within a suitable housing(s) for the economical production of several different models of such electrical devices having differing speed selections.  The housing halves are provided with module supporting means and may be perma-nently secured together by adhesive means.  The motor is also characterized by a torsion spring and brush guide arrangement which prevents any contact of the brush springs with the motor commutator.

Abstract: 420D-165 Canada METHOD AND APPARATUS FOR MONITORING  LIGHT SIGNALS FROM LIQUID MEDIUM                           Abstract In processes for detection and measuring a sub-stance or condition in a fluid medium by the effect of the substance or condition on a light emitting sub-stance, such as luminous microorganisms, disposed in the medium, a method and apparatus is provided for de-termining the effect of the medium on the light signal due to the medium absorbancy or other factor which is independent of the effect of the substance or condition on the light emitting substance.  This is accomplished by deriving from the transmittance of the fluid medium using an external light source the expected transmit-tance of the fluid medium containing the light emitting substance according to the expression   where A is the absorbancy of the fluid, c is the con-centration of the absorbing substance and D is the mean absorbtion path length of the photons emitted.  The expected transmittancy is applied to the observed transmittancy of the test sample to obtain the trans-mittancy of the test sample independently of the opti-cal effects of the medium.     A cell design is disclosed for determining the ab-sorbancy of the fluid medium using a single instrument.

Abstract: ABSTRACT OF THE DISCLOSURE          Time base errors in PAL subcarrier reference bursts, created in part by the operation of a video tape recorder, are detected by the recorder and used for detect-ing the phase shift error in PAL phase angle switching between bursts on adjacent video signal lines which existed before the video signal was recorded.  The video tape recorder timing errors detected on the PAL bursts are first detected after the 90° phase angle between successive PAL bursts has been eliminated.  Two sample and hold units then are alter-nately strobed, each at a point in time during a given tape recorder head pass wherein the error signals are normally most accurate, such that a first burst timing error is retained in one such unit and a next burst timing error is retained in said second unit.  The outputs of these two sample and hold units are filtered and combined in an integrator for generating a voltage control signal whose amplitude varies as a function of the preexisting burst shift error.  This control voltage is fed to a phase shift unit which operates in response thereto to modify the phase of subsequent off-tape color reference bursts before error detection has been performed on such subsequent bursts.
